Poisons of the same kind (but with varying rarity and/or race) were stacking - poisons stacking with two varieties of the same base type was never intended and was removed. eg. You can now stack Wyvern with Manticore, or Manticore with Arachna, but not Wyvern with Wyvern, or Manticore with Manticore.

Updated FMOD version

Item drop tables tweaked - players will see less Normal, Fine and Masterwork grade items as they get deeper into the game. They'll see more Legendary and Epic items instead
